MANUFACTURE OF BLOTTlNG-PAPER.

SPECIFICATION forming part of Letters Patent No. 333,146, dated December 29, 1885.

Application filed May 18, 1885. Serial No.165,842. (Specimens) T0 at whom it may concern:

Be it known that I, CHARLES SUMNER MUROH, of Boston, in the county of Suffolk, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in the Manufacture of Blotting-Paper; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawing, which is a transverse section of a sheet of blotting-paper of my improved kind.

This improved manufacture of blotting-paper is capable on one side only of it of absorbing writing-ink, the other side of the sheet being covered with a lining layer or comp0- sit-ion, such as will not only render it very smooth, but impervious to such ink, though capable of receiving printers ink, or such as will dry on it without penetrating it.

Sheets of thick blotting-paper as usually made are absorbent of writingink when applied to either face of each of such sheets, and consequently when such a sheet has printing or an advertisement printed on one face of it parties using it are very apt to apply the printed face to the ink to be absorbed. As a consequence, the printing becomes soon covered more or less with the ink, so as to be wholly or partly illegible. By having the printed face a non-absorbent of writing-ink all such difficulty is avoided.

In carrying out my invention I cover one side of the sheet A of bibulous card-board or paper with a water-proof facing or lining or composition, a, such as when applied .to a surface having upon it writing-ink in a liquid state will not absorb such, such facing, lining,

position has been spread on the bibulous sheet, J

I usually calender such facing, lining, or composition by passing the sheet between rollers adapted to smooth the water-proofed or resisting surface only.

I claim as a new or improved manufacture 1. A sheet or card of blotting-paper having one side or surface absorbent of writing-ink and the opposite side or surface covered with a water proof or resisting facing, lining, or composition, all being substantially as set forth.

2. A sheet or card of blotting-paper having one side 01' surface readily absorbent of writing-ink and the opposite side or surface covered with a calendered water-proof or resisting lining or composition, all being substantially as set forth.
